Replying to $1 grand or less, winter car

Decided selling my car was a bad idea for college so now I am going to buy a POS beater to ferry me to the ski hill.  Needs to be 1k or less.  So far I have been looking at a 97~ish AWD minivan and 92-95 legacy's.  I am not getting a jeep or really any SUV, the gas mileage is way too shitty.  The minivan I can sleep in comfortably, bake, and haul.  I am leaning towards that, it's just that they are few and far between.

Thoughts?  Better ideas?

Criteria is:
1. Cheap
2. AWD/4WD
3. Good MPG
